Detailed Description

Macro Definition Documentation

◆ HTTP_CONTENT_ENCODING_INIT

#define HTTP_CONTENT_ENCODING_INIT ( )

Initializer for structure http_content_encoding_t.

A static http_content_encoding_t structure must be initialized with the HTTP_CONTENT_ENCODING_INIT() macro. For instance,

http_content_encoding_t http_content_encoding = HTTP_CONTENT_ENCODING_INIT;
#define HTTP_CONTENT_ENCODING_INIT()
Initializer for structure http_content_encoding_t.
Definition http_protos.h:11842

◆ HTTPTAG_CONTENT_ENCODING

#define HTTPTAG_CONTENT_ENCODING (   x)

Tag list item for pointer to a Content-Encoding header object.

The HTTPTAG_CONTENT_ENCODING() macro is used to include a tag item with a pointer to a http_content_encoding_t object in a tag list.

Parameters
xpointer to a http_content_encoding_t header structure, or NULL.

◆ HTTPTAG_CONTENT_ENCODING_STR

#define HTTPTAG_CONTENT_ENCODING_STR (   s)

Tag list item for string with Content-Encoding header value.

The HTTPTAG_CONTENT_ENCODING_STR() macro is used to include a tag item with a string containing value of a http_content_encoding_t header in a tag list.

Parameters
spointer to a string containing http_content_encoding_t value, or NULL.

The HTTPTAG_CONTENT_ENCODING_STR string can be converted to a http_content_encoding_t header structure by giving the string s has second argument to function http_content_encoding_make().

Enumeration Type Documentation

Enumerator
http_content_encoding_hash 

Hash of Content-Encoding header.

Function Documentation

◆ http_content_encoding_copy()

http_content_encoding_t * http_content_encoding_copy ( su_home_t home,
http_content_encoding_t const *  hdr 
)
inline

Copy a http_content_encoding_t header structure.

The function http_content_encoding_copy() copies a header structure hdr. If the header structure hdr contains a reference (hdr->h_next) to a list of headers, all the headers in that list are copied, too. The function uses given memory home to allocate all the memory areas used to copy the header structure hdr.

Parameters
homememory home used to allocate new structure
hdrpointer to the header structure to be duplicated

When copying, only the header structure and parameter lists attached to it are duplicated. The new header structure retains all the references to the strings within the old header, including the encoding of the old header, if present.

Example
content_encoding = http_content_encoding_copy(home, http->http_content_encoding);
http_content_encoding_t * http_content_encoding_copy(su_home_t *home, http_content_encoding_t const *hdr))
Copy a http_content_encoding_t header structure.
Definition http_protos.h:12036
Returns
The function http_content_encoding_copy() returns a pointer to newly copied header structure, or NULL upon an error.

◆ http_content_encoding_dup()

http_content_encoding_t * http_content_encoding_dup ( su_home_t home,
http_content_encoding_t const *  hdr 
)
inline

Duplicate (deep copy) http_content_encoding_t.

The function http_content_encoding_dup() duplicates a header structure hdr. If the header structure hdr contains a reference (hdr->x_next) to a list of headers, all the headers in the list are duplicated, too.

Parameters
homememory home used to allocate new structure
hdrheader structure to be duplicated

When duplicating, all parameter lists and non-constant strings attached to the header are copied, too. The function uses given memory home to allocate all the memory areas used to copy the header.

Example
content_encoding = http_content_encoding_dup(home, http->http_content_encoding);
http_content_encoding_t * http_content_encoding_dup(su_home_t *home, http_content_encoding_t const *hdr))
Duplicate (deep copy) http_content_encoding_t.
Definition http_protos.h:12029
Returns
The function http_content_encoding_dup() returns a pointer to the newly duplicated http_content_encoding_t header structure, or NULL upon an error.

◆ http_content_encoding_format()

http_content_encoding_t * http_content_encoding_format ( su_home_t home,
char const *  fmt,
  ... 
)
inline

Make a Content-Encoding header from formatting result.

The function http_content_encoding_format() makes a new Content-Encoding header object using formatting result as its value. The function first prints the arguments according to the format fmt specified. Then it allocates a new header structure, and uses the formatting result as the header value.

Parameters
homememory home used to allocate new header structure.
fmtstring used as a printf()-style format
...argument list for format
Note
This function is usually implemented as a macro calling msg_header_format().
Returns
The function http_content_encoding_format() returns a pointer to newly makes header structure, or NULL upon an error.

◆ http_content_encoding_init()

http_content_encoding_t * http_content_encoding_init ( http_content_encoding_t  x[1])
inline

Initialize a structure http_content_encoding_t.

An http_content_encoding_t structure can be initialized with the http_content_encoding_init() function/macro. For instance,

http_content_encoding_t http_content_encoding;
http_content_encoding_init(&http_content_encoding);
http_content_encoding_t * http_content_encoding_init(http_content_encoding_t x[1])
Initialize a structure http_content_encoding_t.
Definition http_protos.h:11858

◆ http_content_encoding_make()

http_content_encoding_t * http_content_encoding_make ( su_home_t home,
char const *  s 
)
inline

Make a header structure http_content_encoding_t.

The function http_content_encoding_make() makes a new http_content_encoding_t header structure. It allocates a new header structure, and decodes the string s as the value of the structure.

Parameters
homememory home used to allocate new header structure.
sstring to be decoded as value of the new header structure
Note
This function is usually implemented as a macro calling http_header_make().
Returns
The function http_content_encoding_make() returns a pointer to newly maked http_content_encoding_t header structure, or NULL upon an error.

◆ http_is_content_encoding()

int http_is_content_encoding ( http_header_t const *  header)
inline

Test if header object is instance of http_content_encoding_t.

The function http_is_content_encoding() returns true (nonzero) if the header class is an instance of Content-Encoding header object and false (zero) otherwise.

Parameters
headerpointer to the header structure to be tested
Returns
The function http_is_xcontent_encoding() returns true (nonzero) if the header object is an instance of header content_encoding and false (zero) otherwise.

Variable Documentation

◆ http_content_encoding_class

msg_hclass_t http_content_encoding_class[]
extern

Header class for HTTP Content-Encoding header.

The header class http_content_encoding_class defines how a HTTP Content-Encoding header is parsed and printed. It also contains methods used by HTTP parser and other functions to manipulate the http_content_encoding_t header structure.
